Abstract
The echeline genus Leptenchelys is recognized as monotypic and differs markedly from Muraenichthys. Schismorhynchus, genus novum, is erected for Muraenichthys labialis Seale. The genus Muraenichthys contains 19 known species in the tropical, subtropical, and temperate Indo-Pacific Ocean. M. chilensis, a new species showing affinities to southern Australian congeners, is the first known from the New World. The present distribution of Muraenichthys and of the closely related genera Schultzidia and Schismorhynchus is perhaps explained by paleogeography, paleoclimatology, and adult habitat preferences. Muraenichthys species may be grouped by differences in posterior nostril condition, dentition, and head pore placement. The following changes in taxonomy are proposed : Leptenchelys pinnaceps Schultz = Callechelys melanotaenia Bleeker. Muraenichthys tasmaniensis McCulloch and Scolenchelys tasmaniensis smithi Whitley = Muraenichthys vermiformis Peters. M. ogilbyi Fowler = M. macropterus Bleeker.
